Theoretical plate
Webb1 okt. 2011 · Limitations of equilibrium stages. Many packed column designs for distillation, absorption and stripping follow this path: 1. The task of the column is first defined by an equilibrium stage simulation. (Equilibrium stages are also called theoretical stages or theoretical plates.) 2. The column task is expressed as a profile of column … Webb"height equivalent to a theoretical plate" published on by Oxford University Press.

WebbOne obvious way to increase the number of plates is to increase the length of the column. Doubling the length doubles the number of theoretical plates. One cautionary note about … WebbIn their original theoretical model of chromatography, Martin and Synge divided the chromatographic column into discrete sections—what they called theoretical plates —in …
WebbThe variance per unit length of the column is taken as the ratio of the column length to the column efficiency in theoretical plates. The van Deemter equation is a hyperbolic function that predicts that there is an optimum velocity at which there will be the minimum variance per unit column length and, thence, a maximum efficiency.
A theoretical plate in many separation processes is a hypothetical zone or stage in which two phases, such as the liquid and vapor phases of a substance, establish an equilibrium with each other. Such equilibrium stages may also be referred to as an equilibrium stage, ideal stage, or a theoretical tray.
